NAME
       PDF::API3::Compat::API2::Basic::TTF::OldCmap - Character	map table

       This module is deprecated

DESCRIPTION
       Looks after the character map. The primary structure used for handling
       a cmap is the PDF::API3::Compat::API2::Basic::TTF::Segarr which handles
       the segmented arrays of format 4	tables,	and in a simpler form for
       format 0	tables.

       Due to the complexity of	working	with segmented arrays, most of the
       handling	of such	arrays is via methods rather than via instance
       variables.

       One important feature of	a format 4 table is that it always contains a
       segment with a final address of 0xFFFF. If you are creating a table
       from scratch this is important (although
       PDF::API3::Compat::API2::Basic::TTF::Segarr can work quite happily
       without it).

INSTANCE VARIABLES
       The instance variables listed here are not preceeded by a space due to
       their emulating structural information in the font.

       Num Number of subtables in this table

       Tables
	   An array of subtables ([0..Num-1])

       Each subtables also has its own instance	variables which	are, again,
       not preceeded by	a space.

       Platform
	   The platform	number for this	subtable

       Encoding
	   The encoding	number for this	subtable

       Format
	   Gives the stored format of this subtable

       Ver Gives the version (or language) information for this	subtable

       val This	points to a PDF::API3::Compat::API2::Basic::TTF::Segarr	which
	   contains the	content	of the particular subtable.

METHODS
   $t->read
       Reads the cmap into memory. Format 4 subtables read the whole subtable
       and fill	in the segmented array accordingly.

       Format 2	subtables are not read at all.

   $t->ms_lookup($uni)
       Given a Unicode value in	the MS table (Platform 3, Encoding 1) locates
       that table and looks up the appropriate glyph number from it.

   $t->find_ms
       Finds the Microsoft Unicode table and sets the "mstable"	instance
       variable	to it if found.	Returns	the table it finds.

   $t->out($fh)
       Writes out a cmap table to a filehandle.	If it has not been read, then
       just copies from	input file to output

   @map	= $t->reverse([$num])
       Returns a reverse map of	the table of given number or the Microsoft
       cmap. I.e. given	a glyph	gives the Unicode value	for it.

BUGS
       o   No support for format 2 tables (MBCS)
